PCR Tests for Travel

From Monday 4 October 2021, the rules for international travel to England have changed. These simplified rules for travel from countries not on the red list now depend on your Covid vaccination status.

If you have been fully vaccinated for at least 14 days:

  • under an approved vaccination program in the UK, Europe, or US
  • with a full course of the Oxford/AstraZeneca, Pfizer BioNTech, Moderna or Janssen vaccines from a relevant public health body in Australia, Antigua and Barbuda, Barbados, Bahrain, Brunei, Canada, Dominica, Israel, Japan, Kuwait, Malaysia, New Zealand, Qatar, Saudi Arabia, Singapore, South Korea or Taiwan – mixing between two-dose vaccines (Oxford/AstraZeneca, Pfizer BioNTech, Moderna) in this list is also recognised.

You must:

  • book and pay for a Day 2 COVID-19 test – to be taken after arrival in England
  • complete your passenger locator form – any time in the 48 hours before you arrive in England
  • take a COVID-19 test on or before day 2 after you arrive in England.

You must follow these rules if you:

  • do not qualify under the fully vaccinated rules
  • are partially vaccinated
  • are not vaccinated.

Before you travel to England you must:

  • take a pre-departure COVID-19 test – to be taken in the 3 days before you travel to England
  • book and pay for day 2 and day 8 COVID-19 tests – to be taken after arrival in England
  • complete your passenger locator form – any time in the 48 hours before you arrive in England.

After you arrive in England you must:

  • quarantine at home or in the place you are staying for 10 days
  • take a COVID-19 test on or before day 2 and on or after day 8.

You may be able to end quarantine early if you pay for a private COVID-19 test through the Test to Release scheme.

If you are fully vaccinated you will need to take a coronavirus (COVID-19) PCR test on or before Day 2 after you arrive in the UK.

If you are NOT fully vaccinated you will need to take a coronavirus (COVID-19) PCR test on or before Day 2 and on or after Day 8 after you arrive in the UK. These tests must be booked before you travel.

Children aged 4 and under do not need to take any coronavirus (COVID-19) tests.

You will need the booking test ID number for the coronavirus tests you must take after arriving in the UK.

Your Medwyn booking reference number will be a 7 digit number (13 digits for bookings prior to 6 April) and will be included on your confirmation email. This will be prefixed with “MEDOH” when completing your Passenger Locator Form.

If applicable, name Medwyn Occupational Health as the provider for your Day 5 Test to Release swab to end self-isolation early.

Your Medwyn booking reference number will be a 7 digit number (13 digits for bookings prior to 6 April) and will be included on your confirmation email. This will be prefixed with “MEDOH” when completing your Passenger Locator Form.

Yes – you must take these tests and quarantine, even though you provided a negative test result to enter England.

The day you arrive in England is counted as Day zero (0). If you arrive, for example, on Tuesday then your first day of quarantine is Wednesday and second day is Thursday. You can have your Day 2 test on Tuesday, Wednesday or Thursday in this example. This first test is designed to help identify any potentially harmful variants of COVID-19 at the earliest opportunity.

UK Government guidance states, changing addresses during quarantine can only happen under certain circumstances. These are:-

  • a legal obligation requires you to change address, such as when you’re a child whose parents live separately, and you need to move between homes as part of a shared custody agreement
  • it’s necessary and permissible for you to stay overnight at accommodation before travelling to the place where you will be quarantining for the remaining period.

If you still require a change of quarantine address, you must provide full details of each address where you will quarantine on the passenger locator form.

If, in exceptional circumstances, you cannot remain where you’re staying, you can move to a new place to quarantine and you must complete a new passenger locator form as soon as possible.

It is not possible to say if you had the virus when the test was done. Therefore, you must take another test, or self-isolate for 10 days from the day after your test date.

Yes, there is a requirement by the UK government to conduct genomic sequencing on all positive test results from Day 2 tests. This is included in the overall cost of the testing package.

You can shorten your quarantine period if you pay for a coronavirus (COVID-19) test after isolating for 5 days. This is known as the Test to Release for International Travel scheme. If you are planning to use the Test to Release scheme, you must still take a test on or before Day 2 and on or after Day 8. Even if you get a negative result from your Test to Release and are released from self-isolation, you still need to take a test on or after Day 8 to check that you do not have COVID-19.

The Test to Release scheme is not available to anyone who has been in or through any country that is on the travel ban red list in the 10 days before arrival in England.

The cost of our UK Arrival tests is shown on our website. We continuously aim to reduce our costs with suppliers to provide you with the best possible value tests and highest quality service.

If sent by post, your result will be available approximately 24 hours after receipt at lab. Please remember the postal service will require an additional 24 hours for the sample to arrive at the lab beforehand. This could take longer if a sample is posted on a Saturday or Sunday.

Rapid Antigen Tests for Travel

A number of countries, including the USA, Germany, France and Italy accept antigen tests. You should check the destination country for their COVID-19 entry requirements. Medwyn’s antigen test has a high level of accuracy and meets the UK’s standards for sensitivity, specificity and viral load.

When choosing a COVID-19 antigen test appointment check carefully how many hours before arrival in the destination country you are required to have a negative test result. It is your responsibility to make sure that your destination accepts this test. If you need guidance, the UK government travel advice website provides detailed country entry requirement information at

Yes, wherever you are travelling from, all passengers entering the UK are required to take a COVID-19 test in the 3 days before departure. You must have proof of a negative COVID-19 test to travel to England from abroad. Children aged under 11 do not need to test. Results and certificates are emailed in 1 hour.

For individuals travelling during the COVID-19 pandemic remove the hassle and inconvenience of finding a testing provider abroad by taking a test kit away with you. 

Medwyn only uses the Flowflex Antigen test that meets UK Government Border Entry performance standards of ≥97% specificity, ≥80% sensitivity at viral loads above 100,000 copies/ml.

The PCR test detects the genetic material in the COVID-19 virus called RNA. When the swab sample reaches the lab, a solution known as a ‘reagent’ is added. If there is virus present this reagent starts a ‘chain reaction’ and creates billions of copies of the genetic material in the virus so that there is enough that it can be detected and analysed by scientists to provide a positive result. This test is also known as an RNA, genetic, molecular, viral detection or swab test.

A Rapid Antigen test looks for the presence of specific proteins called antigens based on the surface of the virus from a nose or throat  swab sample and is not as sensitive as the PCR test in detecting COVID-19.

You should always check the testing entry requirements for the country you are visiting before you book an antigen test to check the results will be valid. 


97.1% (83.8%-99.9%) – 95% Confidence Intervals


99.6% (97.7%-99.9%) – 95% Confidence Intervals

Limit of detection:

1.6×102 TCID50/mL

The Rapid Antigen (lateral flow) Test is much quicker in delivering results than a PCR test. Your results will be ready within 15-20 minutes after your swab sample has been applied to the device. 

Your Fit to Fly Certificate is provided at the same time you attend a clinic appointment or emailed to your preferred email account approximately 2 hours after your remote video test.

Once you have purchased your antigen test kit you will be be asked to book a date and time for your remote antigen test. The weblink for your appointment will allow you to securely log in for to your video consultation from your mobile device or laptop. You will be sent an email and SMS reminder before the appointment so you don’t forget.

At the test appointment your identity will be confirmed. Your swab test will be supervised by one of our professional healthcare advisors and your test results should be available after approximately 15 minutes. You will be asked to submit photo evidence of your test result online so your certificate can be issued from Medwyn OH by email and you may then travel overseas.

If your test result is inconclusive this indicates you ‘may’ be infected with coronavirus, or the antigen test was unable to confirm a definite negative or positive result. In this situation it is advised to repeat your test with a further sampling kit. If the result is still is still inconclusive you should be tested with a molecular PCR test to exclude coronavirus.

If you test result is positive there is a high probability you are infected with COVID-19. You will not be able to travel without a negative molecular PCR test which is considered the ‘gold standard’ for identifying SARS-CoV-2 (COVID-19). You should contact a healthcare provider in your local destination to organise testing. If you are in the UK contact NHS 119.
